Pronunciation

  • Brazil: /ˈse.ku/[1]
  • Portugal: /ˈse.ku/[1]

Forms

seco (feminine seca, masculine plural secos, feminine plural secas, comparable, comparative mais seco, superlative o mais seco or sequíssimo, diminutive sequinho, augmentative secão)[1] Bluteau heads the word seco, ou secco, and secco was a common spelling in the 18th century.[2][3] Wiktionary also lists the pre-reform spelling sêco.[1]

Etymology

It is inherited from Latin siccus (“dry”), written Old Galician-Portuguese seco in the oldest texts.[4][5][1] Houaiss dates it to the 13th century from Cunha's medieval slips.[4]

The same Latin word is Galician seco, Spanish seco, Catalan sec, French sec, Italian secco and Romanian sec.[5][6][1] In Spanish it is found from the earliest texts, and as a personal name in documents from 905.[7]

De Vaan connects the Latin adjective with a root meaning “to dry up”, seen in sesc (“dry, barren”), असश्चुषी (asaścuṣī, “not drying up”) and sèkti, but notes that it is unclear how such a form would give the Latin word, so that the etymology remains uncertain; an older view joined it to a root “to pour”.[8] Wiktionary takes it back to *seyk-.[1]

Earliest recorded meaning

The Cantigas de Santa Maria already use the adjective of wood: come madeira mui seca de teito “like very dry roof timber”.[9] The Crónica Troiana speaks of things that began to burn ca estauã secas “because they were dry”, and of an olive branch that had been dry for days.[9]

Semantic evolution

Bluteau (1712) explains seco first as one of the four qualities of the old natural philosophy, the opposite of moist, and then of anything with little moisture, such as dried figs or a dry mouth.[2] Morais (1789) adds the figurative senses “curt in speech, harsh in character” and “unmoved by feelings”, and a series of phrases: missa seca, a mass in which the priest does not consecrate;[10] ama seca, a nurse who does not breastfeed;[10] em seco, out of the water; and dar em seco, to run aground.[10]

Modern Portuguese uses the adjective of dried foods (bacalhau seco, carne seca), of a sound without resonance, of an unadorned style, and of a dry wine.[4][11] In Brazil it also means “eager, longing” (seco por).[4][12] As a noun it names dry ground, a sandbank left by the ebb in northern Brazil, and, in the plural, dry goods, as in secos e molhados “groceries”.[4][13]

Timeline

  • 1712 – Bluteau heads the word seco, ou secco.[2]
